Distribution and habitat Įchinacea paradoxa var. paradoxa has a baseline chromosome number of x = 11, like most Echinacea plants. neglecta - pink or white rays Oklahoma and Texas - Bush's purple coneflower Įchinacea paradoxa var. paradoxa - yellow rays - Arkansas and Missouri - yellow coneflower or Ozark coneflower The central head is dome-shaped and dark reddish brown to nearly black. Each flower head is about 5–6 cm (2–2.5 in) across. One plant can produce several flower heads, each with white, pink, or yellow ray florets surrounding a central head of numerous disk florets. The basal leaves are 8–45 cm (3–18 in) long and narrowly elliptic to lanceolate, and the stem leaves are 4–35 cm (2–14 in) long and linear to narrowly elliptic or narrowly lanceolate. They are alternate, becoming shorter higher up on the stem, and they are completely absent on the upper two-thirds of the stem. Most of the leaves are basal leaves with smooth margins. Description Įchinacea paradoxa is a perennial herb up to 90 cm (3 ft) tall with multiple, slightly hairy stems arising from the rootstock. It is native to southern Missouri, Arkansas, and south-central Oklahoma, It is listed as threatened in Arkansas. neglectaĮchinacea paradoxa, the yellow coneflower, Bush's purple coneflower, or Ozark coneflower, is a North American species of flowering plant in the family Asteraceae. neglecta (McGregor) Binns, B.R.Baum & Arnason, syn of var.

This plant is in part distinguished from black-eyed Susan ( R. Other common names for this plant include thin-leaved coneflower (for thin leaves) and three-lobed coneflower (for three-lobed leaves and species name). Lower leaves are ovate to ovate-cordate with long petioles, and upper leaves are less rounded and sessile. Some of the leaves are 3-lobed (less frequently 5- or 7-lobed). Leaves are thin and rough-textured on both sides. Daisy-like flowers (to 1 1/2” diameter) featuring 6-12 yellow rays and brown-purple center disks bloom profusely from summer to fall. This is a densely-branched plant that typically grows to 2-3’ (less frequently to 5’) tall. In Missouri, it typically occurs in wet woods along streams, alluvial thickets, rocky slopes at the base of bluffs and along roadsides throughout the state except for the far southeastern corner (Steyermark). Rudbeckia triloba, commonly called brown-eyed Susan, is a coarse, weedy, somewhat hairy, clump-forming, densely-branched biennial or short-lived perennial that is native from New England to Minnesota south to Georgia and Oklahoma.
